from anywhere farther south along the Atlantic coast of America. No doubt the fact that 

 there is no record of the Thresher for Georges Bank is accidental. But the paucity of re- 

 ported captures westward and southward from the Block Island-Woods Hole region can- 

 not be explained thus, for so striking is the Thresher in general aspect that any specimen 

 taken is likely to be reported in the daily press, if not in strictly scientific literature. Actu- 

 ally, we have found but one positive record of it for Rhode Island and Connecticut; four 

 for Long Island, New York; one near New York; three in recent years for New Jersey; 

 one for Maryland; two for Cape Lookout, North Carolina (from which it appears that 

 few come inshore close enough along this sector to be picked up in the pound nets) . While 

 Threshers have been described as rather numerous at times among the Florida Keys, there 

 are only three or four reports of it along the east coast of Florida, including a small one 

 from Miami in the Museum of Comparative Zoology. One has been reported to us from 

 Biloxi, Mississippi.'" Nor does it appear to be any more plentiful anywhere farther to the 

 south, where published captures total only three, one being for the Havana region, one for 

 Santa Catherina, Brazil, and one for northern Argentina (Lat. 38° S.). It has not been 

 reported from Bermuda. 



In the northern sector of its range the Thresher appears only in spring, summer or 

 autumn, being wholly absent in winter. But nothing is known of its seasonal incidence any- 

 where else in the western Atlantic.
